How to Generate Random Permutations with Python's itertools Library
The code provided is a Python script that uses the random and itertools libraries to generate random permutations of five balls with different colors. The script defines two functions: get_permutations and print_random_set. The get_permutations function takes three parameters: desired, num_new_colours, and x, y, z. It returns a list of all possible permutations that satisfy the conditions defined by the variables x, y, and z. The function uses a loop to generate random permutations until it finds the desired number of permutations.
